REMOVABLE FIREARM LOCK ERTABLE IN THE F ARM EJEG; PORT ed Ja 2, 1969 United States Patent 3,605,311 REMOVABLE FIREARM LOCK INSERTABLE IN THE FIREARM EJECTION PORT Robert Hermann, P.O. Box 114, Stronghurst, Ill. 61480 Filed Jan. 22, 1969, Ser. No. 793,006 Int. Cl. F41c 27/00 U.S. Cl. 42-1N 1 Claim ABSTRACT OF THE DISCLOSURE A device for placement into the ejection port or opening of a gun which will have a key for advancing a bolt that will prevent the removal of the device from the gun, thus rendering the gun unfireable.

This invention relates to devices for firearms which will prevent them from being fired.

It is therefore the main purpose of this invention to provide a fire arm lock which will consist of a block portion insertable within the ejection opening of the action of the gun in order to prevent the gun from being fired.

Still another object of this invention is to provide a lock which will be opened by key means insertable into the cylinder of the device, the key causing a locking bolt to be advanced or retracted from an opening through the block, the locking bolt advanced externally of the block preventing the block from being removed from the ejection opening of the gun.

A further object of this invention is to provide a firearm lock of which the block portion may be made in various sizes to fit various ejection port openings of guns and the locking bolt portion serves to prevent the removal of the device from the action of the gun.

Other objects of this invention are to provide a firearm lock device which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efiicient in operation.

These and other objects will become readily apparent upon a study of the following specification together with the accompanying drawing wherein:

FIG. 1 shows a plan view of the firearm lock installed within a gun, which is shown in phantom lines;

FIG. 2 is an enlarged plan view of the lock shown removed from FIG. 1 and partially broken away;

FIG. 3 is a cross-sectional view taken along the lines 33 of FIG. 2; and

FIG. 4 is a side elevation of the present invention showing the lock bolt retracted.

According to this invention, a firearm lock consists of an elongated rectangular block 11 made of material of any suitable density. An opening 12 olfset in block 11 3,605,311 Patented Sept. 20, 1971 slidably receives a cylinder housing 13 having a lock cylinder 14 with a conventional keyhole opening 15 for the insertion of a key (not shown). The cylinder housing 13 is secured in place within opening 12 of block 11 by means of a screw fastener 16 to block 11. Block 11 of lock 10 is received within the ejection (shell) opening 17 of gun 18. The lock bolt 19 is slidable within the opening 20 of block 11.

In use, block 11 of lock 10 is placed into the ejection opening 17 of gun 18- and the lock bolt 19 when advanced outward toward the stock end of gun 18 and thus renders gun 18 inoperative.

In order to remove lock 10 and block 11 from gun 18, the key is placed in opening 15 of cylinder 14 and when the key is rotated the lock bolt 19 is retracted into block 11 which will free block 11 to be lifted from the ejection opening 17 in order to render the gun 1 8 fireable.

When lock 10 and block 11 is in place within the ejection opening 17, the mechanism of gun 18 is in effect disabled so that gun 18 may not be fired.

It shall further be noted that the advanced lock bolt of lock 10 will prevent the removal from the gun 18 by hearing against the interior wall of the action of gun 18 and the block 11 cannot be removed without the key except through the mutilation of the firearm itself.

What I now claim is:

1. A firearm lock for preventing a gun from being fired, comprising in combination, a block, said block being of a configuration so as to fit into an ejection port opening of an action of a gun in order to prevent the mechanism of the action of said gun from firing, and lock bolt means extending from said block for aligning behind an inside wall of one side of said ejection port of said gun, said block having an opening into which a lock housing is fitted, said lock housing containing a rotatable cylinder that can be selectively secured or made rotatably free respective to said housing by means of a key removably receivable into an exposed end of said rotable cylinder, said lock housing including a slide bolt, said slide bolt being slideable outwardly of a side of said housing and through a side hole in said block so to project beyond and behind said inside wall on one side of said ejection port of said gun, and a fastening screw for securing said lock housing to said block.
